How the purifier works

Wynd keeps your personal space free from particulates, including allergens, germs, and industrial pollution (PM2.5).

Wynd cleans these particles out quickly. Despite its small form factor, Wynd can deliver over 8 liters of clean air per second.


Designing for air flow

Our engineering lead, Eric, is a former aerospace engineer who worked on the design of jet and rocket turbine blades before joining Wynd. He used his airflow expertise to craft Wynd’s patent-pending fluid dynamics.

We designed a low-turbulence, high-airflow system that keeps Wynd small while enabling it to clean a high volume of air and stay quiet.

Watch Eric discuss how he designed some of Wynd's airflow features:

 Early iterations of Wynd's fluid dynamics

Early iterations of Wynd's fluid dynamics. We tested over a hundred iterations of the mechanical design to optimize air flow to generate clean air quickly, lower noise, and decrease "mixing" of surrounding air so that the clean air generated stays clean at a distance



Wynd contains a medical-grade air filter, capable of purifying particles as small as 0.3um (1 / 210th the average thickness of human hair).

The filter is lined with an antimicrobial layer lined with silver to keep it clean from microbes such as bacteria and mold. As air passes through this filter, the particulate pollutants are removed and any residual germs are killed off, and purified air flows out into your environment.
The filter typically lasts for 3 months in a polluted environment (with an average AQI of 200). But don't worry about having to calculate it—we do it for you. Replacing filters is automated: By tracking how polluted the air is around the filter—as well as Wynd’s airflow level and usage duration—we can tell you how used up the filter is and alert you when it’s time to order a replacement.


Replacing the filter is way easier than on cars or house filters: With Wynd, just pop the old one out and pop the new one in.
